Just tested this morning through Worksite Labs. They are indeed accepted by Hawaii, as they are part of an alliance with Hawaiian Airlines. Testing took no more than 5 minutes from check-in to sealing our swabs in the provided bags for 4 people. It is done entirely within your vehicle. They quote that you will receive your test results within 36 ours. All 4 of us received them within 6 hours. Easy to obtain the official document directly from Worksite Labs and post it to the Hawaii Safe Travels website. The safe travels website accepted them almost immediately. Now just waiting until less than 24 hours before our flight to fill out the health questionnaire to obtain the QR code.
